What is the function of an Automatic Voltage Regulator (AVR) on an HV generator?
Direct Answer
Option A: Control generator field excitation to maintain steady terminal voltage under changing load
The Automatic Voltage Regulator (AVR) maintains generator terminal voltage by adjusting the field excitation current in response to load fluctuations. This regulation is critical for system stability, ensuring that voltage remains within specified limits to protect connected equipment from over-voltage or under-voltage conditions during varying operational demands on board.
